In line with our back away slowly policy, here's a chess like one...
An 8x8 board with alternating black and white squares (a chess board) has two diagonally opposite corners removed.
You are given a set of rectangular dominos, each one can cover exactly two squares.
Is it possible to cover every remaining square on the board without stacking or going over the edge of the board.
Yes or no, and explain your logic.

You have as many dominos as may be required.

NO! because each domino occupies both a black and white square at the same time, therefore with two of the same color square removed, only 30 dominoes could fit on the board. the 31st is excluded!!

Thank you.

edit: heard it before, very easy.

Ok, here's one...
To pay off his gambling debts a father has bet his daughter in a game of chance.
A merchant is to put a black stone and a white stone in a sack, the girl is to remove one stone. If it is white, the debt is cleared and the daughter goes home.
If it is black, the debt is cleared and she is now the property of the merchant.
The girl notices that the merchant has put two black stones in the sack but is not allowed to tell anyone. (part of the wager)
What is the probability that she can escape her predicament and why?

have the merchant say the stone that is left in the bag.

He will say black in which case everyone else will think she has chosen white, under the circumstances she is to be let go.

I don't ask the questions here. I answer them.

But here's one for the hell of it.

WIthout the aid of any measuring device,

How can you use a transparent 16-oz mug to measure a volume of water that is exactly 8 oz.?

Fair enough, but as regards the question, all I have is the one jug, no other items other than the water?

All you have is one mug and a water spout of some sort. That is it. You have nothing else on hand...other than your body parts.

edit: for the purpose of this exercise, we shall say that this mug is a perfect cylinder.

Here goes, put in the water to be measured, draw a mark on the outside, pour this into another receptacle. Fill the jug to the mark with water, then put the original water back in. if it comes to the top, I know I had exactly 8 oz. (ooh, I hate imperial measures!)

In which case the other receptacle is my mouth, and the mark is my finger...?

easier answer.

fill the mug about 2/3 full of water. then tilt it so the water pours off. When the water level reaches the same height as the uplifted mug bottom, then the vessel is indeed exactly half full.

edit: no body parts required!! that was just to throw you off!!!!

Ah, sorry, I was trying not to assume anything about the geometry of the mug, but it was obviously a perfect cylinder. Nice one.
